Converting to E85: What tools of the trade are needed to be successful?
I did a brief search and found more info from questions about how much power from, and blah blah. But not much info on what I will need in order to start using E85. Thinking I want to tune and run E85..
So from the info I found, I will need a larger capacity fuel pump, I do.. I need larger fuel injectors, I have.. And I need a way to make it all work, Neptune RTP..
My question is: Would the Walbro high pressure 255 and 440cc injectors be enough to get going on E85? I read a couple folks out there using 440cc injectors, don't remember what vehicle (may have been honda).
Anyone who HAS converted offer any insight? Thanks!

I forgot to ask about fuel pressure though, are you running an adjustable FPR?
At 3 bar fuel pressure, the 440's will run out at around 200whp on E85 and 250whp on gas I believe. You could go a little higher if you increase your fuel pressure, but I would go with bigger injectors for sure.
Fuel Injector Calculator
Only other critical component to change out IMO is the fuel lines.

technically speaking, you need parts that are compatible with e85, not just able to flow more. This means pump, injectors, and filter that are specifically labelled as compatible with e85. Anything that isn't specified to be compatible risks being damaged by the alcohol.
That being said, I ran a walbro 255HP for several years on e60-e70 with zero issues, and it still flowed like new when I pulled it out to go bigger. I also ran DSM 450's and RC750's on e60-e70 for the same timespan. Both were affected negatively. It wasn't permanent damage though, 20 minutes in an injector cleaner with a special chemical mix cleaned em right up like new.
Also to note, you won't see any power gains from going to e85 unless your setup actually requires higher octane than what's available at the pump. Well, you might see a 3% gain in power, but that's not even enough to feel in the butt dyno. With a setup requiring higher octane than pump though, especially boosted motors, you could see a 5%-30% gain in power, based on several variables
